Project

Assessment of Human Exposure to Metabolic CO2 in ventilated rooms

Location

Greater Copenhagen area

Present standards define maximum CO2 concentration level in the air inhaled by occupants. The amount of outdoor air supplied to the room is controlled to keep the CO2 concentration equal or slightly below the allowed maximum CO2 level. The indoor CO2 concentration is often measured in only one location in the room - either in the exhaust room air or at one of the walls. However, measurements in only one point does not correctly represent the actual CO2 concentration in the entire occupied zone including in the inhaled air of the occupants. The project will investigate the effect of occupant density (i.e. heat load), distance between the occupants, location of the exhaust diffuser and supply airflow rate on CO2 concentration in the inhaled air and the CO2 concentration measured at the exhaust, walls or above occupants. For this purpose, experiments with human subjects and a thermal breathing manikin will be conducted in a room with mechanical ventilation. The results from this project will be used to improve the methodology for CO2 based design of building ventilation. 

This project is planned to start 1 August 2019 till 31 December 2019.
